Building GraalVM native images with Bazel

After you install the rules and setup your GraalVM repository, you can easily use it to build a native image using the native-image tool, from a standard Bazel java_library or java_binary target.

Native image example

Note This sample is present in the rules_graalvm repository at example/native. See examples.

In Main.java:

public class Main {
    public static void main(String args[]) {
        System.out.println("Hello, GraalVM Native!");
    }
}

In BUILD.bazel:

load("@rules_java//java:defs.bzl", "java_library")
load("@rules_graalvm//graalvm:defs.bzl", "native_image")

java_library(
    name = "main",
    srcs = ["Main.java"],
)

native_image(
    name = "native",
    deps = [":main"],
    main_class = "Main",
)

Then, from your terminal:

bazel build //some/package:native
